Washington State Estate Tax 2026: Exemption, Rates, and the Split-Year Change
Washington imposes one of the most consequential state estate taxes in the country — a $3,000,000 exemption that hits middle-class Seattle homeowners, tech employees, and families with appreciated real estate well before the $15,000,000 federal threshold applies. 2026 is also a two-period year: a dramatic rate rollback signed into law in March 2026 lowered the top rate from 35% back to 20% effective July 1, 2026. Families inheriting from Washington residents — or doing estate planning in Washington — need to understand both periods.
- Exemption (Jan 1–June 30, 2026): $3,076,000 per decedent.1
- Exemption (July 1, 2026+): $3,000,000 per decedent (inflation-adjusted annually going forward).2
- Rates (Jan 1–June 30, 2026): 10%–35% — the elevated rate schedule from EHB 2021 (effective July 2025), with a 35% top bracket on taxable estates above approximately $9 million.1
- Rates (July 1, 2026+): 10%–20% — restored by ESB 6347 (signed March 2026), effective July 1, 2026.2
- No WA inheritance tax: Washington does not tax beneficiaries by their relationship to the decedent. The estate pays before distribution.
- No WA gift tax: Washington has no state gift tax. Lifetime gifts permanently reduce the Washington taxable estate with no state penalty.3
- No portability: Washington does not recognize the federal DSUE election. Each Washington estate gets one exemption — couples cannot share unused exemption between spouses.3
- Community property state: Community property assets receive a full double step-up in cost basis at the first spouse's death under IRC §1014(b)(6).
- Federal gap: The federal estate tax exemption is $15,000,000 (permanently set by OBBBA, July 2025). Estates between $3M and $15M face Washington estate tax with no federal offset.
- Filing: Washington Estate Tax Return, due 9 months from date of death. Filed with the Washington Department of Revenue.4
Why Washington's estate tax catches more families than most expect
Washington is the only state in the country with no personal income tax but a meaningful estate tax. Residents often focus on the income tax advantage while overlooking the estate tax exposure that builds quietly over decades through rising home values and retirement savings.
- A Seattle-area home purchased in 2005 for $350,000 may now be worth $900,000–$1,400,000 or more.
- Add a 401(k) ($400K–$900K), brokerage accounts ($200K–$600K), and life insurance — and a household that considers itself comfortable, not wealthy, may have a gross estate well above $3M.
- Washington has one of the lowest estate tax exemptions in the country. A couple with a combined estate of $6M who does not plan faces Washington estate tax of approximately $390,000 at the second death against only one $3M exemption.
- Tech workers in the Seattle metro with RSUs, deferred compensation, and employer 401(k)s can accumulate taxable estates in their 50s that exceed the exemption while still earning, not yet retired.
- The $3M exemption is per decedent — not per couple. At first death, everything may pass to the surviving spouse under the unlimited marital deduction with no tax — but at second death, the combined estate faces only one $3M exemption. Without planning, this is a common and costly oversight.
2026 is a split year: what changed and why it matters
Washington's estate tax rate schedule changed significantly twice in twelve months, creating a two-period structure for 2026 that depends on the date of death.
The rate increase: EHB 2021 (effective July 1, 2025)
The Washington Legislature passed Engrossed House Bill 2021 in 2025, which dramatically increased estate tax rates effective July 1, 2025. The new schedule raised the top marginal rate from 20% to 35% and compressed brackets to reach the highest rates faster. EHB 2021 applied to all deaths occurring on or after July 1, 2025, including those in the first half of 2026.
The rollback: ESB 6347 (effective July 1, 2026)
In March 2026, Governor Ferguson signed Engrossed Senate Bill 6347, rolling back the estate tax rate schedule to pre-July 2025 levels effective July 1, 2026.2 The top rate returns to 20%. ESB 6347 also froze the exemption at $3,000,000 with annual inflation adjustments going forward.
| Date of Death | Exemption | Top Rate | Authority |
|---|---|---|---|
| Jan 1–June 30, 2026 | $3,076,000 | 35% | EHB 2021 (July 2025) |
| July 1, 2026 and after | $3,000,000 | 20% | ESB 6347 (March 2026) |
The practical impact: a Washington resident with an $8M estate dying before July 1 may face approximately $500,000–$700,000 more in Washington estate tax than the same estate dying on or after July 1 — potentially over $1 million more at higher estate values. Estate planners in Washington have been focused on this date for clients in terminal decline or with health uncertainty.
Washington estate tax rates: July 1, 2026 and after
Effective July 1, 2026, Washington's estate tax uses the restored 10%–20% graduated rate schedule. Rates apply to the Washington taxable estate — the gross estate minus allowable deductions and the $3,000,000 exemption amount. Estates at or below the exemption owe nothing.2
| Washington Taxable Estate (Excess Over $3M Exemption) | Marginal Rate on That Slice |
|---|---|
| First $1,000,000 ($3M–$4M gross estate) | 10% |
| $1M–$2M excess ($4M–$5M gross estate) | 14% |
| $2M–$3M excess ($5M–$6M gross estate) | 15% |
| $3M–$4M excess ($6M–$7M gross estate) | 16% |
| $4M–$6M excess ($7M–$9M gross estate) | 18% |
| $6M–$7M excess ($9M–$10M gross estate) | 19% |
| $7M–$9M excess ($10M–$12M gross estate) | 19.5% |
| Over $9M excess (over $12M gross estate) | 20% |
| Gross Estate Value | WA Taxable Estate | Approx. WA Estate Tax | Effective Rate (on full estate) |
|---|---|---|---|
| $3,000,000 | $0 | $0 | 0% |
| $4,000,000 | $1,000,000 | $100,000 | 2.5% |
| $5,000,000 | $2,000,000 | $240,000 | 4.8% |
| $6,000,000 | $3,000,000 | $390,000 | 6.5% |
| $7,000,000 | $4,000,000 | $550,000 | 7.9% |
| $9,000,000 | $6,000,000 | $910,000 | 10.1% |
| $10,000,000 | $7,000,000 | $1,100,000 | 11.0% |
| $12,000,000 | $9,000,000 | $1,490,000 | 12.4% |
| $15,000,000 | $12,000,000 | $2,090,000 | 13.9% |
Calculated using the ESB 6347 rate schedule applied to WA taxable estate (gross minus $3M exemption). Assumes no other deductions. Exact amounts depend on allowable deductions, property types, and filing details — consult a Washington estate attorney for precise computation.2
For the Jan 1–June 30, 2026 period (EHB 2021 rates, top rate 35%), estates that exceeded the $3,076,000 exemption faced a more compressed and aggressive bracket structure. The WA Department of Revenue's Table W for that period provides the exact computation. Estates of decedents who died before July 1 should use the EHB 2021 rate table available from the WA DOR and consult an estate attorney — the tax amounts can be meaningfully higher than the July 1+ examples above.
The federal-Washington estate tax gap
The most important planning concept in Washington estate tax is the gap between the state exemption and the federal exemption:
| Level | 2026 Exemption | Notes |
|---|---|---|
| Federal estate tax | $15,000,000 per person | Permanently set by OBBBA (July 2025); spousal portability available |
| Washington estate tax | $3,000,000 per person (July 1+) | Inflation-adjusted; no portability |
| The gap | $12,000,000 | Estates in this range owe WA estate tax but zero federal estate tax |
For the vast majority of Washington families, the federal estate tax is not a concern — their estates are well below $15M. But the Washington estate tax catches families from roughly $3M to $15M who owe state taxes with no federal offset whatsoever. A family with a $6M estate faces approximately $390,000 in Washington estate tax and $0 in federal estate tax. This is "invisible" to most people who think of "estate taxes" as something only the ultra-wealthy owe.
What assets are included in the Washington taxable estate
| Asset Type | Included in WA Taxable Estate? | Notes |
|---|---|---|
| Primary residence / WA real estate | Yes | Date-of-death fair market value; heirs receive step-up basis (IRC §1014) regardless of estate tax owed |
| Community property (WA is community property state) | 50% of community property | At first spouse's death, decedent's 50% share included. Full double step-up on community property under IRC §1014(b)(6) — a significant advantage over common-law states |
| Brokerage / investment accounts | Yes | FMV at date of death; step-up basis resets for heirs |
| IRAs and 401(k)s | Yes | Full account balance included in gross estate; heirs separately owe income tax on distributions |
| Life insurance (estate as beneficiary) | Yes | Included under IRC §2042 |
| Life insurance (named individual beneficiary) | Included if IRC §2042 applies | Excluded if decedent had no incidents of ownership and estate is not beneficiary |
| Revocable living trust assets | Yes | Pass outside probate but remain in gross estate under IRC §2038 |
| Out-of-state real estate | Generally no WA estate tax | Out-of-state real property is taxed by the property's state, not Washington; WA estate tax applies to residents' worldwide estate minus out-of-state real property |
| Non-WA resident with WA real estate | Yes — WA real estate only | WA imposes estate tax on WA-situs real property of non-residents on a pro-rata basis |
| Business interests | Yes — date-of-death FMV | Minority interest and lack-of-marketability discounts may apply; qualified farm deduction available (see below) |
| Farm property (qualifying) | Unlimited deduction | WA qualified farm deduction removes 100% of qualifying farm assets — see Farm Deduction section below |
The double-tax burden on inherited retirement accounts deserves special attention: a $1.5M IRA is counted in the gross estate (pushing a $5M estate toward the WA taxable range), and the beneficiary separately owes income tax on distributions over the 10-year rule period. See Inherited IRA 10-Year Rule Guide for distribution strategies and Inherited IRA Drawdown Optimizer to model bracket-fill scenarios.
Washington is a community property state — a step-up basis advantage
Washington is one of nine community property states. For married couples, this creates a significant step-up basis advantage at the first spouse's death that does not exist in common-law states.
Under IRC §1014(b)(6), when a spouse dies in a community property state, both halves of community property receive a step-up in basis — not just the decedent's 50% share. A couple in Washington who bought a house in 2003 for $300,000 (community property, cost basis = $300K) that is now worth $1,200,000 will see the entire $1,200,000 become the heir's basis — not just the decedent's $600K share.
- Washington (community property): House purchased for $300K, now worth $1.2M. At first spouse's death, surviving spouse's basis in the entire house steps up to $1.2M. If surviving spouse sells immediately after inheriting: $0 capital gain. Federal LTCG savings: up to $135,000 (15% on $900K gain) — in addition to WA's own capital gains tax savings.
- Common-law state (e.g., Oregon): Same house. Surviving spouse's existing 50% share ($600K current value, $150K basis) does NOT step up. Only the decedent's 50% steps up. Surviving spouse retains $150K basis in their original half. If they sell, they owe capital gains on $450K of gain on their half.
- The community property double step-up is one of the most valuable but least understood benefits of being a Washington resident — and is directly relevant to estate planning and inheritance timing decisions.
See Step-Up Basis Complete Guide and Step-Up Basis Tax Calculator for more on how basis resets work at death.
Married couples: no portability and what to do instead
The federal estate tax allows surviving spouses to use the deceased spouse's unused exemption (the "DSUE" election, filed via Form 706 within 9 months of death). A married couple can effectively share up to a $30M combined federal exemption.
Washington does not recognize portability.3 Each Washington estate gets exactly one $3M exemption. If the first spouse to die leaves everything outright to the surviving spouse via the unlimited marital deduction, the surviving spouse's estate at second death may face Washington estate tax on the entire combined estate against only one $3M exemption.
- Wife dies in 2026 with a $3.5M estate (home $1.8M + IRA $900K + brokerage $800K); everything passes outright to husband via unlimited marital deduction → $0 WA estate tax at her death
- Husband now has a $7M estate (his $3.5M + hers $3.5M, plus any growth)
- At his death: $7M estate, only one $3M WA exemption → WA taxable estate = $4M → WA estate tax ≈ $550,000
- A credit shelter trust at wife's death could have sheltered $3M from husband's estate → reducing his taxable estate from $4M to $1M → WA estate tax ≈ $100,000 → saving approximately $450,000
Credit shelter trusts (bypass trusts) — essential for Washington married couples
At the first spouse's death, assets equal to the Washington exemption ($3M) are placed in a credit shelter trust rather than passing outright to the surviving spouse. The trust benefits the surviving spouse during their lifetime and then passes to children or other beneficiaries without being included in the survivor's taxable estate. For a couple with a $7M combined estate, proper use of credit shelter trusts can reduce Washington estate tax from $550,000 to approximately $100,000 or less — a potential saving of $450,000+.
No Washington gift tax — and no lookback period
Washington has never imposed a state gift tax.3 Residents can make unlimited lifetime gifts without incurring any Washington tax at the time of the gift — and unlike New York (which adds back gifts made within 3 years of death to the NY taxable estate), Washington has no clawback period. A gift completed before death is permanently out of the Washington taxable estate regardless of timing.
- Federal annual gift exclusion is $19,000 per recipient in 2026 (indexed for inflation). A couple with three adult children can give $19,000 × 3 recipients × 2 spouses = $114,000 per year with no federal gift tax return required.
- Over 5 years, that's $570,000 removed from the Washington taxable estate — potentially the difference between owing $100,000 in WA estate tax and owing nothing.
- Gifts above the annual exclusion use the federal lifetime exemption ($15M per person) but still have no Washington consequence — the gift is permanently out of the WA estate on the day it's completed.
- 529 superfunding ($95,000 per beneficiary in 2026, treated as 5 years of annual exclusion gifts) can transfer large amounts to grandchildren immediately while reducing the WA taxable estate.
Washington qualified farm deduction
Washington offers an unlimited estate tax deduction for qualifying farm property — one of the most generous farm exemptions of any state with an estate tax.5 If the qualifying conditions are met, 100% of farm asset value is deducted from the Washington taxable estate, regardless of size.
Key requirements for the WA qualified farm deduction:
- The decedent must be a U.S. citizen or resident.
- Farm property must pass to a qualified heir (family member or qualified farm entity).
- Farm property must have been used in farming at the time of the decedent's death by the decedent or a family member.
- Farm property must represent at least 50% of the adjusted gross estate.
- No recapture period — unlike the federal §2032A special use valuation, Washington does not require heirs to continue farming after death to retain the deduction.
The 50% threshold means farm owners should monitor the ratio of farm-to-non-farm assets. If the farm drops below 50% of the estate, the deduction is lost entirely. Gifting non-farm assets to stay above the threshold — or to reduce total estate size — is a key planning lever for Washington farm families.
Washington spousal personal residence exclusion
Washington offers a separate exclusion for a surviving spouse's personal residence. The surviving spouse can exclude a portion of the value of a personal residence from the Washington gross estate at the first spouse's death. For married couples with significant home equity, this can work in concert with the credit shelter trust strategy and the community property double step-up benefit. Consult the Washington Department of Revenue and a Washington estate planning attorney for current limits and qualifying requirements, as this provision interacts with other deductions and the specific fact pattern matters.
Filing requirements
Who must file
The personal representative of a Washington resident decedent must file a Washington Estate Tax Return with the WA Department of Revenue if the gross estate exceeds the applicable exclusion amount ($3,076,000 for deaths before July 1, 2026; $3,000,000 for deaths on or after July 1, 2026).4
Deadline: 9 months from date of death
The Washington estate tax return is due 9 months from the date of death.4 Extensions of time to file may be requested, but tax owed must be paid by the original deadline to avoid interest and penalties.
Payment
Washington does not have a separate inheritance tax filing requirement for beneficiaries. The estate pays before distributions. If assets have already been distributed and the estate cannot pay, the executor may have personal liability — another reason beneficiaries should confirm an estate tax return was filed before accepting distributions from a large estate.
Non-resident decedents with Washington real estate
Washington imposes estate tax on Washington-situs real property owned by non-residents on a pro-rated basis. An Oregon or California resident who owns a vacation home or investment property in Washington may have Washington estate tax obligations on that property. A Washington estate attorney should evaluate before distributions are made from any estate containing WA real property.
How Washington compares to other state estate taxes
| State | 2026 Exemption | Max Rate | Portability | Gift Clawback | Notable Feature |
|---|---|---|---|---|---|
| Oregon | $1,000,000 | 16% | No | No | Lowest exemption in country; catches many homeowners |
| Massachusetts | $2,000,000 | 16% | No | No | No cliff; low exemption hits real estate-rich estates |
| Washington | $3,000,000 (July 1+) | 20% | No | No | Rates rolled back July 1; community property double step-up; unlimited farm deduction |
| Illinois | $4,000,000 | 16% | No | No | No income tax; no portability; real estate drives many estates in |
| New York | $7,350,000 | 16% | No | Yes — 3 years | Cliff provision — estates above 105% of exemption lose it entirely |
| Maryland | $5,000,000 | 16% | No | No | Only state with both estate tax AND inheritance tax |
| Federal (all states) | $15,000,000 | 40% | Yes | No | Permanent (OBBBA); inflation-indexed |
Planning strategies to reduce Washington estate tax
Washington's combination of a $3M exemption, no portability, no gift tax, no gift clawback, community property rules, and an unlimited farm deduction creates a specific set of planning opportunities. These strategies work best when implemented well before death.
1. Credit shelter trusts — essential for married couples
At the first spouse's death, assets equal to the Washington exemption are placed in a credit shelter trust rather than passing outright to the surviving spouse. This shelters $3M from the survivor's taxable estate, preserving that exemption permanently. For a couple with a combined $7M estate, this strategy alone can save $450,000+ in Washington estate tax. Every married Washington couple with a combined estate above $3M should evaluate whether their current estate plan uses credit shelter trusts.
2. Systematic lifetime gifting
Because Washington has no gift tax and no gift clawback, systematic gifting is the most straightforward way to reduce the taxable estate. Use the federal annual gift exclusion ($19,000 per recipient in 2026). Gifts above the annual exclusion use the federal lifetime exemption ($15M) but still have no Washington consequence. A couple with three adult children can remove $114,000 per year from the Washington taxable estate. Over a decade, that's $1.14M — potentially dropping a $4M estate below the $3M exemption entirely.
3. Irrevocable Life Insurance Trusts (ILITs)
Life insurance owned by the decedent at death is included in the Washington gross estate under IRC §2042. Transferring a policy to an irrevocable life insurance trust removes it from the estate. A second-to-die (survivorship) policy held in an ILIT can fund Washington estate tax at second death while remaining outside both spouses' estates. Because Washington has no gift clawback, the main constraint is the federal 3-year transfer rule (policy included in federal gross estate if decedent dies within 3 years of transfer).
4. Community property planning
Washington's community property regime provides a double step-up basis benefit at the first spouse's death that is unavailable in common-law states. However, community property must be properly titled and maintained as community property — mixing community and separate property (commingling) can convert community property to separate property and lose the double step-up. Married Washington residents should review titling of their assets with an estate attorney to ensure community property classification is preserved.
5. Spousal Lifetime Access Trusts (SLATs)
A SLAT allows one spouse to gift assets to an irrevocable trust for the benefit of the other spouse, removing those assets from both estates while preserving indirect access through the beneficiary spouse. Washington's no-clawback rule makes SLATs especially effective — assets contributed are immediately and permanently removed from the Washington gross estate. Mutual SLATs require careful structuring to avoid the reciprocal trust doctrine.
6. Qualified farm deduction planning
For Washington farm families, maintaining the 50% farm-to-total-estate ratio is essential. Consider gifting non-farm assets to reduce total estate size while keeping farm assets above the 50% threshold. Unlike the federal §2032A election, Washington's farm deduction has no post-death recapture requirement — heirs are not required to continue farming after inheriting.
7. Charitable planning
Charitable bequests reduce the Washington taxable estate dollar-for-dollar. A charitable remainder trust (CRT) provides income to the donor during life, with the remainder passing to charity at death. For families with estates modestly above the $3M threshold and charitable intent, integrating a CRT can reduce or eliminate the Washington estate tax while achieving philanthropic goals. See Charitable Giving from an Inheritance.
What Washington estate tax means if you're inheriting from a WA resident
If you're an heir inheriting from a Washington resident with a significant estate, here is what the estate tax means in practice:
- You don't personally file or pay the Washington estate tax. The executor handles it from estate assets before making distributions to heirs.
- You may receive less than the gross estate value. A $5M estate with a $240,000 Washington estate tax bill distributes less to heirs than the gross value suggests. Factor this into your expectations when named as a beneficiary of a large Washington estate.
- Ask the executor whether a Washington estate tax return is being filed. If the estate exceeds $3M and no return is being prepared, that is a red flag requiring investigation.
- Watch the 9-month filing deadline. The executor has 9 months from date of death to file and pay. Delays generate interest charges that further reduce the estate available for distribution.
- Step-up basis still applies regardless of estate tax. Even if the estate paid Washington estate tax, you as the heir receive a step-up in cost basis on inherited assets under IRC §1014. See Step-Up Basis Complete Guide.
- IRAs are double-taxed. Retirement accounts are counted in the gross estate for Washington estate tax and you separately owe income tax on distributions as a beneficiary. A $1.5M IRA from a Washington estate may have contributed to a Washington estate tax bill — and you still owe income tax on every distribution over the 10-year rule period. See Inherited IRA 10-Year Rule Guide.
- Community property step-up is your friend. If the decedent was married and assets were held as community property, you may inherit with a basis reset on the surviving spouse's share as well — not just the decedent's half. This can significantly reduce your capital gains tax exposure when you sell inherited assets.
Frequently asked questions
My parent died in Washington with a $2.8M estate. Is there Washington estate tax?
No. For deaths on or after July 1, 2026, the Washington estate tax exemption is $3,000,000. A $2.8M estate is fully exempt. For deaths before July 1, 2026, the exemption was $3,076,000 — so a $2.8M estate was also exempt. No Washington estate tax return needs to be filed.
My parent died in Washington with a $5M estate. How much Washington estate tax is owed?
For deaths on or after July 1, 2026: WA taxable estate = $5M − $3M = $2M. Tax: 10% on first $1M ($100,000) + 14% on next $1M ($140,000) = approximately $240,000. The exact amount depends on deductions, and the executor should use the Washington DOR rate schedule and consult an estate attorney.
Does Washington recognize the federal portability election?
No. The federal portability election (DSUE via Form 706) does not apply to Washington estate tax. Each Washington estate gets one $3M exemption. A surviving spouse cannot inherit the deceased spouse's unused Washington exemption. This is why credit shelter trusts are critical for married Washington couples — without one, a couple with a $6M combined estate may waste one entire $3M exemption at first death.
Can I reduce Washington estate tax with lifetime gifts?
Yes — effectively. Washington has no state gift tax and no gift clawback period. Gifts completed during life permanently remove assets from the Washington taxable estate on the day they are completed. The federal annual gift exclusion ($19,000 per recipient in 2026) allows systematic transfers. This is one of the most powerful Washington estate tax reduction tools, especially for families with estates modestly above the $3M threshold.
The decedent died in January 2026. Are the old 35% rates or the new 20% rates applicable?
The old 35% top-rate schedule (EHB 2021) applies to all deaths occurring January 1 through June 30, 2026. The exemption for that period is $3,076,000. ESB 6347's 20% top-rate schedule only applies to deaths on or after July 1, 2026. For an estate from a death in January–June 2026, consult the WA Department of Revenue's Table W for the applicable rate computation and work with a Washington estate attorney — the tax due may be substantially higher than under the post-July rules.
I live in Oregon but own a Washington vacation home worth $1M. Does WA estate tax apply?
Potentially, yes. Washington imposes estate tax on WA-situs real property owned by non-residents on a pro-rated basis relative to the total estate. If your total estate is $4M and the Washington property is $1M (25%), Washington estate tax would apply to approximately 25% of any WA estate tax liability. An Oregon or Washington estate attorney should evaluate the specific exposure before making plans or distributions.
What is the Washington estate tax on my inherited house?
The house was counted in the decedent's gross estate for Washington estate tax purposes at its date-of-death fair market value. As an heir, you receive a step-up in basis to that fair market value — meaning your capital gain when you sell starts from the inherited value, not the decedent's original purchase price. You personally do not pay Washington estate tax; the estate paid it before distributing the house to you. See Inherited Real Estate Guide for sell/rent/hold decision analysis.

Get matched with an advisor who understands Washington estate planning
Washington's $3M estate tax exemption — combined with no portability and no gift tax — creates both a significant exposure for middle-class Seattle families and a clear set of strategies to reduce it. A $5M estate may owe $240,000 in Washington estate tax; a $7M estate may owe $550,000. The tax is due 9 months after death, and the strategies that reduce it (credit shelter trusts, systematic gifting, ILITs, SLATs) require planning years before that deadline. A fee-only financial advisor specializing in inheritance and estate planning can model whether your family is exposed to Washington estate tax, evaluate whether your current plan adequately addresses the no-portability trap, and coordinate with your estate attorney on the most effective strategies for your specific situation.
